Heat exchangers are used to increase the efficiency of climate systems, such as boilers, air conditioners, recuperators, etc. D.,. In addition, their use allows you to reduce heating costs.
These devices are also used in systems based on the effect of the heat pump – heat exchangers and the internal water circuit supply heat to the desired part of the building.
Heat exchangers are also used in systems where water bodies or groundwater act as a heat source. The use of the device helps to organize the system along the closed contour, when the heat from the reservoir is transmitted to the desecious water of the contour. This excludes premature aging and clogging of the pipeline.
In climatic systems, plate heat exchangers are most often used, which occupy less space, but have high indicators of heat transfer, practicality and efficiency. According to experts, the work of systems with plate heat exchangers by 20-30% more effective than the operation of systems with leather heat exchangers.
As a rule, plate heat exchangers are made of alloy steel or copper, and persistent nickel -containing materials are in the quality of the solder. Such devices can withstand pressure up to 31 bar and temperature up to 185 ° C.
A plate heat exchanger is a fastened plates with each other, between which the coolant circulates. Before fastening on the plates, the channels of the coolant movement should be created. The thickness of the plates can be 0.3-0.8 millimeters, and the area can fluctuate, including from the wishes of the user and the input of additional plates into the heat exchanger.
The area of the plate is the main physical parameter of plate heat exchangers, and engineers should reduce it as much as possible, while increasing the performance. To achieve this goal, the distance between heat exchangers and the speed of the fluid inside are fixed.
The photographs in this article depicts highly effective plate heat exchangers Alfa Leval, which have proven themselves in cold temperatures and at high pressure drops, which set the pace of demand for Alpha Leval’s goods in the Russian Far North. Alpha Leval and other manufacturers, the company Teplosnab is possible to purchase these, as well as other models of heat exchangers.
